Trial Summary Introduction Root rot of cucumber, caused by Pythium aphanidermatum, can lead to significant crop losses, weakening and even killing young plants when transplanted onto previously infested, re-used rockwool slabs. Inoculum build up in early crops when temperatures are low are often symptomless. However, late summer crops under higher temperatures can be badly affected, especially during the early establishment phase post-planting. Safe, effective and approved treatment options are limited and identifying new products with activity against oomycete pathogens will be of benefit to a number of crop sectors.
Methodology A mature hydroponic cucumber crop was inoculated in the root zone with cultures of Pythium aphanidermatum. Cucumber seedling bait plants were used to confirm presence and spread of the pathogen within the rockwool before planting new young cucumber plants onto the infested slabs one month after inoculation. Each plot comprised one rockwool slab containing 3 plants and plots were replicated 6 times. Four conventional fungicides and two biopesticides were tested, alongside untreated and standard (Previcur Energy) controls, by application as drenches to the rockwool blocks. The first treatments were applied immediately after planting and repeated at weekly (biopesticides) or fortnightly (conventional fungicides) intervals, unless otherwise recommended by the manufacturer. Assessments were made, during the life of the crop, of agronomic features (plant height, leaf area, stem diameter and yield) as well as visible disease symptoms (stem base lesions). A final destructive assessment on 1st November 2017 included root vigour, root colour, root coverage of blocks/slabs. Phytotoxicity symptoms were recorded as they were observed, and most phytotoxicity effects were recorded as variance in agronomic features.
Results Symptoms developed slowly in the crop, potentially because ambient temperatures and radiation were low for the time of year and, as a result, plants were less stressed. All plants survived for the duration of the trial as a result of the low-moderate disease levels. Severity of stem base lesions (using a 0-3 severity scale) was therefore used to differentiate between treatments. Data was then converted to a disease index score per plot (0-100 scale) as presented in the table below.

N.B. AHDB 9963 is significantly different from the untreated control, but is not highlighted because disease symptoms are worse than in the untreated control.
Conclusions The pathogen was uniformly distributed in the rockwool slabs across all trial plots, as demonstrated by use of susceptible bait plants. However, disease did not develop rapidly in the newly planted crop. Low to moderate levels of disease were observed as stem base lesions, but lack of crop mortality made visual differences harder to observe. The standard treatment (Previcur Energy) worked well, reducing stem base lesion severity by approximately 75%. Two test products (AHDB 9958 and AHDB 9967) significantly reduced stem base lesions compared to the untreated. Fruit yield was reduced with treatment AHDB 9958 but not with AHDB 9967. However, AHDB 9967 appeared to have a detrimental effect on root development, with reduced coverage of block bases by roots. One treatment (AHDB 9963) caused severe phytotoxicity, with plants wilting, having reduced growth and yield, and having poorly developed roots. These symptoms appear to have caused an increase in disease susceptibility as stem base lesions were higher in this treatment than in the untreated control.
Take home message: One new conventional pesticide (AHDB 9958) and one biopesticide (AHDB 9967) significantly reduced disease symptoms in the trial. One product (AHDB 9963) led to severe phytotoxicity which was linked to difficulties with calculating application rates for its use as a drench in hydroponic systems where there is little buffering in the inert substrate. This is likely to be a complication for other products and we recommend taking particular care with application rate calculations in this scenario. Further work under higher disease pressure would be necessary to better evaluate the performance of promising candidate products to ensure both efficacy and crop safety during higher temperature periods. The results of this trial are already guiding product choices in SCEPTREplus Year 2 projects including field vegetable work (SP 37) and further protected edibles work on root diseases (SP 21). It is also expected that the results will contribute to product choice in crop safety work in the ornamentals sector (SP 33).
Objectives 1. To evaluate the effectiveness of four conventional fungicides and two biopesticides against root

Prior history of site Previous crop: cucumber (June-August 2017) Rockwool slabs from previous cucumber crop reused, as per commercial practice. The slabs were inoculated with cultures of Pythium aphanidermatum whilst the previous crop was in place and bait plants used to confirm presence of active disease in all slabs. The aim of this was to simulate what happens commercially. It was, in effect, a natural means to evenly introduce P. aphanidermatum into the trial area pre-planting.

* DA – days after first application (11/09/2017). Note that AHDB 9958 and AHDB 9959 did not arrive before the start of the trial and so first applications were made on 18/09/2017.
Assessments were carried out using the following scales: Stem base lesion 0 = no evidence of stem base lesion 1 = slight discolouration to a small area of stem base 2 = moderate area of discolouration 3 = severe lesion causing breakdown of tissues and discolouration extending around much of stem base Plant Vigour 0 = Dead 1 = Substantial reduction in overall vigour, but still growing 2 = Reduced vigour compared to healthiest plants- appear healthy but smaller overall 3 = Most vigourous plants in trial Plant Colour 0 = Dead 1 = Substantial yellowing/chlorosis 2 = Paler than healthiest plants in trial, but still green. 3 = Greenest plants in trial. Rooting Strength (assessed at point of block attachment to slab) 0 = No rooting into slab 1 = Only loose attachment by roots into slab 2 = Well attached but some movement possible 3 = Strong and secure attachment to slab Root discoloration 0 = No evidence of root discoloration or decay 1 = <5% roots with discoloration & decay 2 = 5-25% roots with discoloration & decay 3 = > 25% roots with discoloration & decay
Statistical analysis The trial layout was based upon an incomplete Trojan Square design which allowed for variation between rows and columns of plots. ANOVA analysis of the data using Genstat was carried out by Andrew Mead of Rothamsted Research. In this particular implementation of a Trojan square design, the 8 treatments have been assigned both to 2 sub-groups of 4 (as identified by the levels of ps1) and to 4 pairs (as identified by the levels of ps2). This trial layout means that 2 different LSD values were produced for each assessment- one to be used when treatments share a ps2 value, and one to be used when treatments have different ps2 values allocated. These different LSD values are shown at the bottom of results tables in this report. Efficacy was calculated using disease index scores, based on stem base lesion assessments carried out on 2 dates.
Disease Index was calculated using the following formula:
Disease Index = 1(no. scored 1) + 2(no. scored 2) + 3(no. scored 3) x 100 3 (No. of plants assessed) 3
Efficacy has been presented as percentage control, calculated as follows: Percentage control = 1 - Disease index of treatment x 100
Disease index of untreated
Results Phytotoxicity Phytotoxicity was assessed in several ways. 7 days after the first application of treatments an assessment was made of general phytotoxicity symptoms (yellowing, stunting, necrosis) relative to the negative control. Agronomic features such as plant height, leaf area and stem diameter were also measured, along with crop yield, during the life of the crop. These measurements could potentially be indicative of either a phytotoxic effect, or of root infection so the results of these assessments must be considered alongside disease assessments and are discussed later in this report. Severe phytotoxicity was observed in plots treated with AHDB 9963. Two days after the first application plants in these plots were observed to be wilting and when a full assessment was made 5 days later, plants in these plots were stunted, yellowed and necrotic patches were appearing on leaves. See Figure 1.

Agronomic Features Assessments of agronomic features are shown in Table 3. These assessments may highlight disease effects (where root rot is limiting plant growth and development) but in most of these assessments, where the untreated plots are not significantly worse than the standard, differences observed are perhaps most likely to be caused by phytotoxicity.

Root sampling was also carried out and samples inspected microscopically for presence of resting spores (oospores) as an indicator of Pythium infection. Results between replicate samples of the same treatment were very inconsistent and no differences were found between treatments.
Discussion The trial was conducted as described in the protocol, with the following exceptions:
- Treatments AHDB 9958 and AHDB 9959 did not arrive on time to be applied on the day of planting, and so were applied one week late. This had the potential to impact on their efficacy, as their activity was expected to be protectant and not eradicant.
- Due to a calculation error, treatment AHDB 9967 was applied at 0.04% rather than at the 0.4% stated in the protocol.
Disease levels in the trial were expected to be moderate to high due to the level of inoculum used and the effectiveness of this inoculum as proven by the use of bait plants. Planting of the trial was delayed for one week as some test products had not arrived. This delay meant that the test plants were bigger and therefore more robust at planting and got off to a better start on the infested slabs than smaller plants might have. Disease did not reach high levels in the trial and did not cause death of any plants. However, disease symptoms were still observed and the trial provided a moderate test of product efficacy. The standard product (Previcur Energy) performed well, reducing disease, as assessed by stem base lesion severity, by approximately 80% compared to the untreated control. The trial can therefore be considered valid. Assessments of root vigour and discolouration were complicated by phytotoxicity effects in some of the treatments and cannot be clearly attributed to infection by Pythium aphanidermatum. However, clear differences in stem base lesion severity allowed us to identify two effective products. AHDB 9958 and AHDB 9967 both reduced the severity of stem base lesions, although, as discussed above, AHDB 9958 was first applied later than scheduled which may have negatively impacted on its efficacy. These two products did also have some negative impact on the plants. Root strength, plant height and fruit production were all slightly reduced by AHDB 9958, indicating a possible phytotoxic effect
from the product. The application rate of this product should be reconsidered in future work. AHDB 9967 appeared to have a negative impact on root growth (% coverage of block) and fruit yield was slightly reduced. This is a biopesticide product and was applied 7 times on a weekly basis so future work should consider less frequent applications. Handling of this product was slightly less straight forward than others as it foamed a lot when mixed.
One treatment (AHDB 9963) gave severe phytotoxicity even after one application and whilst plants did survive, growth was severely checked and fruit production very poor. Stem base lesion severity was significantly higher with this treatment, possibly due to the weakening of the plant by the product leading to higher infection levels. Other test products also appeared to negatively impact on plant growth, as seen in the agronomic assessments. Treatments AHDB 9963 and AHDB 9960 both reduced plant height, leaf area, stem diameter and fruit yield when compared to the untreated and standard treatments. AHDB 9959 also reduced fruit yield.
Conclusions
- Disease levels were low to moderate in the untreated plots. - The standard product worked well, giving good reduction of stem base lesions. - Two test products gave reductions in stem base lesions although they also negatively
impacted on other aspects of plant growth. - One product gave severe phytotoxicity effects and two others caused slight phytotoxicity. - Calculating appropriate product rates for use as drenches in hydroponic systems can be
challenging and if possible differential dose rates should be included, especially where there is limited prior knowledge available.
- Further work under higher disease pressure would be preferable before drawing firm conclusions and finalising product selection to pursue approved use.
